METHOD OF SUSPENDI NG HIDES IN TANNING.

SPECIFICATION forming part of Letters Patent No. 328,984, dated October 27,1885.

Application filed December 27, 1884. Serial No. 151,327. (No model.)

To all whom it may concern Be it known that I, FRANCIS R. TUTTLE, of Salem, county of Essex, State of Massachusetts, have invented an Improvement in Met-hods of Suspending Hides in Tanning, 850., of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to improvements in a method of suspending hides in vats to be treated; and it consists in first temporarily engaging two connected hooks or clamps to the corners or butt-ends of apair of sides; next, engaging a second pair of connected hooks to the opposite corners or neck ends of said pair of sides, and, lastly, suspending and spacing the pair of sides in a vat by passing the hook-connections over two pins or holders arranged one at each side of said vat, as will be described.

In carrying out my invention I suspend the sides in a vat in pairs by employing flexible connections composed, essentially, of two hooks, spring-catches, or clamps attached to a common cord or short piece of rope, wire,or chain, which is passed around one of a series ofpins secured to each of the side rails now employed in vats, the said hooks or clamps engaging the corners or, say, the butt-ends of two sides, similar hooks or clamps with flexible connections engaging the other corners or neck ends of the two sides, the said flexible connections being passed around a pin in a side rail at the opposite side of the vat, the two suspcndingcords having hooks being passed around one of each ofthe series of pins on the side rails,causing the sides, though sus pended in pairs, to be properly spaced, as in the old method.

Figure 1 shows a vat in section with my invention employed therewith; Fig. 2, a plan view of the vat, partly broken away. Fig. 3 shows in section a vat with a hide suspended as by the method commonly practiced, and Fig. 4 a detail of one of the hooks.

The vat A is provided with the usual side rails, a, having a series of pins, 0. Two hooks, 0, attached to the ends of a short cord, rope, wire, chain, or other suitable connection, f, is engaged with the corners or butt-ends of two sides, 2 '3, when said connection f is passed over a pin or holder, 0, of one of the side rails, to suspend the hides from that rail, after which two other hooks, 6, attached to a second connection, f, is fastened in the other corners or neck ends of the two sides. and the connection passed over a pin or holder, 0, of the rail on the opposite side of the vat, whereupon the two sides will be fully suspended in the vat and spaced apart, so as to be thoroughly acted on by the liquor contained therein.

By this means the sides are quickly and easily suspended and properly spaced, the suspension of two hides, when spaced, only requiring the use ofoue pin of each side rail.

Instead of the hooks e, a spring-clamp,

catch, or any other suitable device that can readily be attached to and detached from the hides may be employed.

In the old plan commonly practiced, Wherein the hide is nailed on opposite sides of the outer bar, it frequently happens that portions of the nails are left in the hide, and when the same is being acted upon in the splitting-machine the knives,striking the nails,are nicked out or materially damaged, so that the knife has to be removed and be reground.

In practice sides will generally be suspended in the vat; but it is obvious that should the hide be small it will not be divided longitudinally, forming sides; but the hooks at the opposite side of the vat may engage the corners ofthe hide at the neck and butt-ends, respectively.

That improvement in the art ofsuspending hides in vats to be treated which consists in first temporarily engaging two connected hooks or clamps, substantially as described, to the corners or butt-ends of a pair of sides, next engaging a second pair of such connected hooks to the oppositecorners or neck ends of the said pair of sides, and, lastly, suspending and spacing the pair of sides in a vat by passing the hoolcconnectious over two pins or holders arranged at opposite sides of said vat, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

. FRANCIS R. TUTTLE.
